Manufacturing of DIN 2638 WN flanges is done by the cutting, forging and casting methods. These manufacturing methods are in accordance with material standards DIN 2638, and below are the respective methods for giving a brief idea to customers:

  • Forging: with the help of a die, a hammer or a press, this manufacturing process compresses the metal block or slabs from a solid state. This in turn increases the strength.
  • Casting: in this manufacturing process, the mold is poured with a molten metal, which forms the desired flange.

There are use cases that reveal welding problems with DIN 2638 PN160 weld neck flanges. This is mainly because of the inappropriate welding practices being employed. Make sure that the surface of flange face is clean from any dirt or other impurities. On the other hand, avoid using excessive heat input. If the product itself turns to be faulty, then don’t worry; immediately ask for replacement.

Distinctive differences emerge because of the different pressure rating for DIN 2638. For instance when comparing flanges of DIN 2638 of PN 100 and PN 160, there is just one difference. In DIN 2638 PN100 welding neck flange, the specific pressure rating condition is only 100 bars. Whereas, for flanges of DIN 2638 PN160, the specific pressure rating is 160 bars. When put for ideal use case, obviously PN160 would win the race as it exhibits high pressure tolerance. Hence it is widely demanded for use case in pressure vessels, oil and gas industries and even in piping systems.
